Strange problems with Fans and RGB - Any ideas?

[JohnAb]

So I noticed recently that my RGB Corsair case fans were not lighting up as normal. Then I noticed that the Corsair AIO fans were not lighting up either. The case fans run off off a Commander Core XT and the AIO fans run odd another controller hub that came with the AIO.

All fans are turning just that I have no control over anything through the hubs. I tried unplugging each hub from the motherboard and trying them individually, reinstalling iCue and I even went back to an old OS backup from Sep last year to eliminate Windows updates or some other drivers.  Same problem. When the PC starts, the fans and RGB run fine, but as soon as Windows starts, the odd behaviour begins, even if iCue is not set to autostart. I'm at a loss right now and I can't believe that both hubs would have failed at the same time. 

Could this be related to the latest BIOS? Trouble is, I can't pinpoint exactly when the issues starting happening. Can't think of anything else that has changed recently. 

I'd really appreciate some ideas or if anyone else has experienced similar problems recently. Thanks.

Forgot to say, I can change the AIO LCD display, but not the ring lighting around the outside. I was going to try uninstalling Armoury Crate, but the fact that my old OS backup doesn't work means that it can't be software or drivers. Everything was working fine at the time of the OS backup. I've also tried forcing firmware updates on both hubs, no change. So I can't think of anything apart from the recent 2305 BIOS update that has changed. Could a BIOS update affect motherboard USB headers? If that's the cause, it would explain why restoring the old OS backup hasn't helped.

So here is a little update. Whilst I think it seems unlikely that my fan/RGB problems are related to BIOS 2305, I watched the POST process when I turned the PC on this morning. 

All of the lights and fans were running normally as soon as I started to POST. Then, half way through the process, I noticed that the RGB ring lights on the AIO LCD turned off again, even before the POST process was finished. That seemed strange to me, as I wasn't even close to loading Windows.

I've got back to BIOS 2204 now, but the fans/RGB problem is the same. Oh well, at least I know what it isn't 🙄

Nobody seems interested in this topic, but I don't care 😂. In the end I worked out that something is wrong with Windows/drivers after all (despite my certainty that it wasn't the issue). I don't know what the problem is yet, but I do know that a fresh Windows install will fix it at least. That's my job for the weekend. It's all of the extra software that takes forever.

Final update - problem solved. It was HWInfo v7.42. The change log says they added detection for Corsair Commander units. I went back to v7.4 and that still version works just fine. I spent far too long working out what the problem was, so I hope this helps somebody. I've also let Corsair know, I bet they've had a flood of reported issues.
